Definitions

  • the invention relates to an apparatus for brewing in particular a multiplicity of consumption units of a hot drink, such as coffee, comprising a combination of a filter pan and a disposable filter cartridge having an axially symmetrical body and fitting said filter pan, the filter pan and the filter cartridge having cooperating parts to provide a water seal when the filter cartridge is put into and rests loosely in the filter pan and water poured on it.
  • a hot drink such as coffee
  • Such an apparatus is for example known from the French patent application 1,506,263.
  • a further point of view is that the filter cartridge expands, owing to the high brewing temperature, which expansion in practice never takes place fully uniformly.
  • the apparatus aims to overcome this drawback. Accordingly the apparatus is characterised in that the cooperating parts exhibit a substan- tailly equal axially symmetrical conicity of between 0° and 45° and define a capillary gap therebetween.
  • clamping upon the introduction of the filter cartridge must exactly be prevented. That is to say, a capillary space must be left between a part of some length of the filter cartridge and a cooperating part of the inner wall of the filter pan. This must be such that sealing is obtained purely by capillary forces.
  • said capillary gap extends over a distance of between and 3 cm. Further the conicity ranges between 1° and 10°, and the cooperating parts have a length of 1-2 cm.
  • the filter cartridge has a substantially radially directed circumferential edge, preferably off-set outwardly, which when the filter cartridge is introduced into the filter pan rests loosely on a substantially radially directed, inwardly projecting circumferential edge of the filter pan. In the operative condition therefore, the filter cartridge rests on a substantially horizontal edge.
  • the capillary gap remaining between the parts of the filter pan and the filter cartridge that cooperate to provide a seal should preferably be between and mm.
  • the body of the filter cartridge must have such a general shape, and the thickness of its material must be such, suiting the nature of the material, that at the temperatures employed, this body has a sufficient dimensional stability.
  • the filter pan will be of metal and the body of the filter cartridge formed with a tolerance not exceeding 0.2 mm with respect to the radial diameter of the cooperating parts.
  • a metal filter pan 1 with an outlet 8 a filter cartridge 2 with a polystyrene filter body 5 of 0.6 mm.
  • This filter body 5 is provided with an outward circumferential collar 6, which when the filter cartridge is introduced rests loosely on the inwardly projecting circumferential edge 7 of the filter pan.
  • the filter cartridge has a web-shaped top filter 3 and a web-shaped bottom filter 4.
  • the bottom filter 4 is supported by a bottom 11 of the filter body with sufficient cut-outs to allow the water to pass unimpeded.
  • the parts of the filter cartridge and the filter pan which cooperate to provide a seal are respectively designated by 9 and 10. They have a conicity of 2°.
  • the capillary gap remaining after the introduction of the filter cartridge in the filter pan is ca. 0.5 mm wide.
  • the ground coffee is designated by 12. For a brew of 1-2 liters, the amount of coffee will range between ca. 40 g. and 100 g.
  • the apparatus according to the invention has been described with reference to coffee. Naturally, the invention is not so limited. Brews or infusions of tea, herbs or chicory, for example, can also be prepared with the apparatus according to the invention.
